Hello, sorry to bother you. May I ask you some questions regarding IQ capture in OpenWiFi? Here is my contact information: c2385405729.
from openwifi.
Hi xianjun, I'm confused about how the RSSI value is obtained, and why is the rssi_half_db_offset 150? If I want to use the 1G band, how should I determine these values?
if (freq_MHz<2412) { rssi_correction = 153; } else if (freq_MHz<=2484) { rssi_correction = 153; } else if (freq_MHz<5160) { rssi_correction = 153; } else if (freq_MHz<=5240) { rssi_correction = 145; } else if (freq_MHz<=5320) { rssi_correction = 145; } else { rssi_correction = 145; }
This is kind of "manual calibration" values.
If the RSSI in your new band is not accurate, you need to add the new calibration/correction value inot that piece of code.
